I've been working on a book about agile project management for enterprise projects. My publisher just gave me a title! "Project Management the Agile Way -- Making It Work in the Enterprise". Look for it in January, 2010.
Until then, the article below is a petty good introduction to some of the top-level ideas. You can down load "What is this Thing Called Agile" from my library at slideshare.com
There are some other materials there you may find interesting. Let me know!
